To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
Install the speakers in a cool, dry, clean place – away from
windows, sources of heat, sources of excessive vibration,
dust, moisture or cold. Avoid sources of electrical humming
(e.g., transformers and motors). To prevent fire or electric
shock, do not expose the speakers to rain or water.
3
To prevent the enclosure from warping or discoloring, do not
expose the speakers to direct sunlight or excessive humidity.
4
Avoid installing the speakers where foreign objects may fall
onto them and/or where they may be exposed to liquid
dripping or splashing.
5
Do not place the following objects on top of the speakers:
– Other components, as they might damage or discolor the
surface of the speakers.
– Burning objects (e.g., candles), as they might cause fire,
damage to the speakers or personal injury.
– Containers of liquid, as they might spill and cause electric
shock to the user or damage to the speakers.
6
Do not place the speakers where they are liable to be knocked
over or struck by falling objects. Stable placement will also
ensure better sound.
7
Placing the speakers on the same shelf or rack as the
turntable can result in feedback.
8
Secure placement or installation is the owner’s responsibility.
YAMAHA is not liable for accidents caused by improper
placement or installation of speakers.
9
If you note distortion, reduce the volume control on your
amplifier. Do not drive your amplifier to the point of
“clipping”. Otherwise, the speakers may be damaged.
10 When using an amplifier with a rated output power higher
than the nominal input power of the speakers, care should be
taken not to exceed the maximum input of the speakers.
with the rear panel facing down on the floor or other surfaces.
4
When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough space around the unit and
avoiding excess humidification. Condensation might cause
fire, damage to the unit, and/or electric shock.
5
Do not cover the rear panel of this unit with a newspaper,
tablecloth, curtain, etc. to avoid obstructing heat radiation. If
the temperature inside the unit rises, it may cause fire,
damage to the unit, or personal injury.
6

dangerous and may cause fire, damage to the unit, and/or
personal injury. YAMAHA is not responsible for damage
resulting from use of this unit with a voltage other than
specified.
8
Super-bass sound reproduced by this unit may cause a
turntable to generate audio feedback. In this case, move the
unit away from the turntable.
9
This unit may be damaged if certain sounds are continuously
output at high volume level. For example, if 20Hz–50Hz sine
waves from a test disc or bass sounds from an electronic
instrument, etc. are continuously output, or if a turntable
stylus touches the surface of a disc, reduce the volume level
to prevent the unit from being damaged.
10 If you hear distorted noise (i.e., unnatural, intermittent
“rapping” or “hammering” sounds) from this unit, reduce the
volume level. Extremely loud movie soundtrack low
frequency, bass-heavy sounds, or similarly loud popular
music passages can damage this unit.
11 Vibration generated by super-bass sound may distort images
on a TV. In this case, move the unit away from the TV set.
11 Do not clean the speakers with chemical solvents as this
might damage the finish. Use a clean, dry cloth.
12 When disconnecting the power cord from the wall outlet,

USING THE SUBWOOFER (SW-P440)
Advanced Yamaha Active Servo
Technology II
QD-BASS TECHNOLOGY
In 1988, Yamaha brought to the speaker systems utilizing
YST (Yamaha Active Servo Technology) to give powerful,
high quality bass reproduction. This technology uses a
direct connection between the amplifier and speaker,
allowing accurate signal transmission and precise speaker
control.
As this technology uses speaker units controlled by the
negative impedance drive of the amplifier and resonance
generated between the cabinet capacity volume and port, it
creates more resonant energy (the “air woofer” concept)
than the standard bass reflex method. This allows for bass
reproduction from much smaller cabinets than was
previously possible.
Yamaha’s newly developed Advanced YST II adds many
refinements to Yamaha Active Servo Technology,
allowing better control of the forces driving the amplifier
and speaker. From the amplifier’s point of view, the
speaker impedance changes depending on the sound
frequency. Yamaha developed a new circuit design
combining negative-impedance and constant-current
drives, which provides a more stable performance and
clear bass reproduction without any murkiness.
QD-BASS (Quatre Dispersion Bass) technology uses
down-firing drivers with square, pyramid-shaped
reflective plates to radiate the sound efficiently in four
horizontal directions. The reflective plates (not used in
competitors' down-firing subwoofers) negate any effects
caused by the floor surface and reduce resonance between
sound waves reflected from the floor and the unit. Also,
most other systems use circular cones, but by radiating in
four directions to avoid the legs of the cabinet, QD-BASS
reduces turbulence caused by reflection from the legs.
Changing the height of the square pyramid varies the
acoustic load, permitting relatively simple high-cut
adjustment and improved band pass properties.
The QD-BASS system provides extraordinary power and
smooth frequency response from an extremely compact
unit. It also allows greater freedom of placement, since the
sound radiates with equal effectiveness in all directions.
